This invention relates to roller bearings, and has for its generalobject to provide such a bearing which will operate with a minimum offriction and which will embodya very efiicient construction of rollerbearings and retaining means for such bearings, whereby they may operateas the sole retainers for an otherwise fully floating sleeve member.

A further object is the provision of a roller bearing assembly of thetype indicated which will embody alternating large and small rollers andprovide novel retaining and thrust means for the roller assembly.

Other and more limited objects will appear from the followingdescription when taken in connection with the accompanyingdrawingwherein Fig. 1 is an end elevation with a portion broken away andFig. 2 is a central longitudinal section, the device embodying myinvention.

Referring now to the drawing, the numeral 23 indicates an outer sleevemember Within which is a floating inner sleeve member 24. Between thesleeves 23 and 24 are a plurality of large rollers 25 alternating withwhich are an equal number of small rollers 25. The small rollers 26 maybe placed so as to contact the adjacent large rollers and either of thesleeves 23 or 24. It will be understood that there will be workingcontact between the small rollers and adjacent large rollers and thatthe rollers are of such sizes that the large ones are slightly spacedapart, for example from one to two one-thousandths of an inch. Thediameters of the rollers will be such that there will be a sufficientclearance for insertion of the rollers longitudinally between the sleevemembers.

A pair ofsplit retaining rings 2'! composed of spring metal may becompressed-and caused to overlap at their ends so as to be introducedinto the space 28 between the sleeves 23 and 24 and allowed to expandand seat themselves in the grooves 29.

The inner sleeve 24 is provided with flanges 24 extending outwardly andadapted to receive therebetween the rollers 25. At the corner formedbetween the bearing surface of the inner sleeve 24 and the flanges 24are grinding cuts 24 It will be noted that the inner surface of therings 21 are in the same plane with the inner surfaces 24 of the flanges24 It will be understood that the length of the rollers is such as toallow free working clearance. It will also be noted that the split rings2] extend over the ends of the large rollers 25 and. form a retainingmeans for the smaller rollers 26. In the event the smaller rollers 26between the sleeves.

should be placed in position to contact the inner sleeve 2:1 instead ofthe outer sleeve 23 as shown, the flanges 24 will form retaining meanstherefor.

In assembling, one of the rings 2'! is preferably placed in position inone of the grooves 29 after which the inner sleeve is partially insertedinto the outer sleeve and the rollers are then inserted The inner sleeveis then brought to the relative position shown in Fig. 2 and the otherring 21 is compressed and intro duced through the space 28 into theposition shown, alternatively the lower ring 21 may be placed in itsgroove, the sleeves 23 and 24 placed in the relative position shown inFig. 2 and the large rollers 25 inserted through a notch 24 in theflange 24 the small rollers 26 inserted through the space 28 between thelarge rollers and the upper ring 21 then inserted. It will be understoodthat in the first method of assembly the notch 24 is omitted.

This application is a division of my copending application Serial No.657,809, filed February 21, 1933, Patent No. 1,972,355 issued September4, 1934.

Having thus described my invention, what I claim is:

1. In a bearing, the combination of an inner journal sleeve member andan outer sleeve memher, a plurality of spaced rollers interposed betweenthe said members, a plurality of smaller rollers interposed. between thefirst mentioned rollers and one of the said members, each of the smallerrollers being in rolling engagement with the two larger rollers adjacentthereto, the inner member having at an end thereof a radially outwardlyprojecting extension, said extension havher, a plurality of spacedrollers interposed between the said members, a plurality of smallerrollers interposed between one of said members and the first mentionedrollers and each in rolling engagement with the two larger rollersadjacent thereto, the inner member being provided adjacent each endthereof with a radially outwardly projecting annular surface adapted toengage the ends of the rollers interposed between the ends of the firstmentioned rollers, the outer member being provided with a radiallyinwardly projecting annular surface at one end thereof cooperating withthe corresponding annular surface of the inner member to engage theadjacent ends of the first mentioned rollers, and the outer member beingprovided adjacent the opposite end thereof with an insertible andremovable ring having a radially inwardly annular surface adjacent thecorresponding annular surface at the adjacent end of the inner member toprovide means for retaining the rollers between said members.
